Tube amplifier to power Sonus Faber speakers?

I'm using wyetech lab ruby 211 with RCA tubes on sonus faber guarneri homage ,a friend is using the same amp but wyetechs 300b version, on his amati futuras ,you should get wyetech labs onyx for the olympica

The Sonus Faber dealer here in SW FL uses fairly large Audio Research tube mono blocks (sorry, I can't remember the models) to power his Olympicas. The sound is top notch.

Frontier-

look into ARC, Conrad Johnson and Rogue Audio for your tube needs. Keep me posted and Happy Listening!

Perhaps consider a hybrid amp (tbe/MOSFET) such as the Butler TDB2250 or the Monad. The 2250 has 250 watts/ch. and the Monad is 100 watts/ch. pure class A...

Hi Frontier1, your speakers though advertised at nominal 4ohms, is not showing the whole picture. As the lab test results show in the link, they have an amp hungry impedance with -phase angle load of 1.7ohms in the bass. They maybe efficient but they are a hard load.

This to me says if you want to get the very best out of them, especially in the bass, you need an amp that gives good current, the ability to almost double it's watts down to 2ohms.
EG:
50w into 8ohms
100w into 4ohms
200w into 2ohms
These amps are good solid state with BJT (bipolar) output stages (not mosfet)This is also why even good P/P tube amps will wimp out a little down low, even with 4ohm taps.
